“Few people in the world have as much insight into President-elect Trump’s philosophies, principles and objectives as Newt Gingrich,” the notice with the subject line “Newt Gingrich fee increase” reads.

“As the senior voice in the Republican Party and advisor to the new administration, Gingrich has been at the forefront of the Republican strategy for the last two years.”

Politico said Gingrich is now charging $25,000 plus ground transportation costs for speeches in Washington, D.C.

The 2012 GOP presidential candidate then charges $60,000 and first class travel for two for each speech east of Chicago, and $75,000 and first class travel for two for every event west of the Windy City.
